WRONG: A 3-d object needs 6 faces for it to look like a 3-d figure Actually the answer is "at least four" - not six. Consider a regular tetrahedron, which is a pyramid with a triangular base. It has four planar faces.
A figure that has at least 3 faces. (ex.) cube, rectangular prism, pyramid, triangular prism and stuff like that.
